How do i go about becoming a club member, and is it one off payment or monthly, as i'de quite happily pay it Way way back in the thread when someone mentioned the FCD...would that solve the original problem? If yes would it still be worth getting the fuel controller as i guess it will not be running the correct air fuel ratio? and how much/ish are they, we talking a few 100 or way more? would that do the job for the time being: http://www.ebay.co.uk/itm/Greddy-emanage-ECU-Toyota-Supra-Aristo-Chaser-JZZ30-JZA80-JZX100-JZS147-1JZ-2JZ-/170871548708?hash=item27c8bceb24 and yea, i guess it's just running better than mine but then my capri is running better than my mkiv at the moment haha and just driving the mkiv around town without boosting it, would that still be bad for it? or is it ok to drive, but just don't floor it till the controller is sorted? i take it if i got it dyno'd, they can't adjust the fueling on the stock ecu if i just have an FCD installed at the time?

Ahh ok, Should i get a Fuel cut defender aswell? or just the fuel controller? and i think my confusion stemmed from that when i typed fuel controller into the internet, things like this came up (which im guessing is incorrect): http://www.ebay.co.uk/itm/Fuel-Pressure-Controller-Adjustable-Toyota-Supra-2JZ-2JZGTE-MK4-GTE-Turbo-0-7Bar-/351469072935?hash=item51d5307227 Im almost 100% certain my friends single turbo (90mm) doesn't have anything but an uprated walbro fuel pump, and stock ecu etc etc...but his runs fine confused. How would i get in contact with the trader/s that you have recommended?

AHHH awesome Many thanks, cheers guys

Ahh this was when i thought they might have been the same thing:p . right back to the original issue with the fuel cut at full power, would the reg need to be changed, or just have an adjustable fuel controller? also where would the fuel controller be installed on the car? does it matter, or just a case of accessibility to adjust it?

So is alright for me to leave it blanked off?

Ahh, where can you find one that will go in place of the old one that will fit in the small gap where the factory one is? and i know it's a stupid question haha, but is a fuel pressure reg and fuel controller the same thing?

Im not running any more than 400-450, so should bigger injectors be needed than stock? Am i wrong in thinking there is a stock fuel pressure reg on the fuel rail that needs to be replaced by an aftermarket one? Or shall the fuel controller just go on the fuel line prior to the rail? And yea, thats all i want at the moment is it to be safe to drive without wrecking a low mile 2j. The light only comes on under full acceleration, when driving normal, it runs perfectly with no lights...and the eml never comes on, but operates as it shows up for a second when the car is started.

Hi, No i just went and checked...turns out the person who did this conversion i think was a bit of a doughnut. The whole fuel system is completely stock. Will be ordering fcd, fuel controller and 450l/h denso fuel pump this weekend...it's got an ar/70 t4 bottom of the range garrett at the moment

Ahh, thanks for all the feedback guys what would you say the max is that i should run on stock injectors and ecu on a single turbo? As im getting it dyno tuned once the fuel cut and new walbro is on next week...

Yea we were both thinking that...but on mine, should the blocked off vacuum from the back off the intake be blocked off? Or should it have to go somewhere?

Looks like the stock ECU to me, and i can't see any FCD. It was converted way before i bought it, and to be honest looks like on a budget

Hi, [GRIN][/GRIN] Since i bought the car i have noticed the vacuum line coming off the rear of the intake has been blocked off with just a piece of hose and a bolt...where is this vac line suposed to go when it was twin turbo and/now it's single turbo'd? As on my friends single turbo supra, it goes behind the bulkhead, and isn't clear to see without taking his dash apart...which he was reluctant to do hahaha

That's exactly how it feels...around 1.5kg/cm2, so about 20-22psi, i don't have a aftermarket boost controller, but have that fairly rough estimate from the boost gauge. Would i need to to uprate the fuel pump aswell?

I did the paper clip test, and nothing came up... It seems to be worse now, under normal driving there is no problem, but when under full power it slams the light on straight away, and it dies down in power completely ever 2ish seconds until you drop out of the power. Between the cut out's it's still running full power. I've tried all possilbe combinations with the trac control, overdrive and manu mode, but nothing makes a difference. Someone mentioned it could be a case of getting a fuel cut defencer? Cheers, Tom

Hi, [/GRIN] I have a single turbo converted (originally TT) Auto JZA80 around 450 at the crank. It previously had the front splitter/spoiler, but was removed for the fitment of the intercooler. The light comes on when under hard acceleration, usually when it shifts to third, and stays on. The car runs perfectly and shows no signs of any problems, however not knowing what the light is really wind me up! [ANGRY][/ANGRY] The link below shows a video of it under acceleration, http://tinypic.com/r/30vchzr/8 Cheers, any help will be very appreciated [GRIN] /vbb/images/smilies/bbcode_grin.gif /vbb/images/smilies/bbcode_grin.gif
